This study tested the null hypothesis that the opacity of RealSeal SE (RSSE) sealer makes light-curing inefficient, while the degree of conversion (DC) is similar regardless of curing method. Fourteen uniradicular teeth were sectioned at 15 mm from the apex. Root canals were instrumented using the Reciproc file system, bulk-filled with RSSE, and divided randomly into two groups (dual-cure or self-cure). DC was determined by micro-Raman spectroscopy at 24 h, 48 h, and 1 week after filling, at 6, 9, and 12 mm from the coronal end...

Bulk-fill resin composites represent an innovative class of dental composite materials, developed to simplify and expedite the restoration process. They can be adequately photopolymerized up to 4–5mm composite thickness and therefore permit a more economical restorative approach as compared to conventional resin composites. The current paper summarizes the most important facts on bulk-fill composite materials and provides recommendations for the successful use of these materials in daily practice based on upto-date in vitro and in vivo research...

Sonication technology has recently been touted to decrease composite viscosity during delivery and may allow better cavity preparation adaptation and minimize voids. The purpose of this investigation was to evaluate the difference between conventional, hand-placed, incremental application of a standard hybrid resin-based composite (RBC) and sonicated application of a bulk-fill RBC in box-type and cylindrical cavity preparations. Experimental restorations were fabricated using molds of box-type or cylindrical preparations...
